Abstract: PROBLEM TO BE SOLVED: To defrost an evaporator quickly without leaving frost by stopping a fan for an arbitrary time before starting defrost operation of the evaporator through a defrost means. SOLUTION: During cooling operation, a microcomputer counts the integrated operating time of a compressor 20 using a function thereof, i.e., a timer, and makes a decision whether the integrated operating time of the counter has reached 8 hours. Upon elapsing 8 hours after previous defrost operation, the microcomputer makes a decision whether the inner temperature is lower than a set level. At a moment when the inner temperature drops below the set level, the fan 11 is stopped for an arbitrary time before starting defrost operation of the evaporator 10 thus enhancing defrost efficiency while eliminating frost.

Abstract: PROBLEM TO BE SOLVED: To solve a problem such that by effecting energization and non-energization of a partitioning part for a part sectioned into different temperature zones at the same timing, though a low temperature section is cooled, at a high temperature section, both heaters for prevention of vapor condensation are energized, and accordingly an excessive chamber load is exerted on a partitioning part, cooling capacity is lowered, and a consumption power amount is increased. SOLUTION: In a method for energizing a plurality of heaters 12 and 14 for prevention of vapor condensation consisting of a refrigerator casing 1 having a high temperature first section and a low temperature second section, and a partition part for the sections and partition parts 11 and 13 for one door and the other door, means to detect the cooling states of the respective sections by various means are established at a control device 18 to be capable of controlling energization of the heaters 12 and 14 for prevention of vapor condensation independently at the respective sections and an energization deciding means therefor. By independently fluctuating the prevention of vapor condensation heater energizing factors of the partition parts 11 and 13 according to an operation state, prevention of vapor condensation is practicable through consumption of reduced energy.

Abstract: PROBLEM TO BE SOLVED: To improve a fluid behavior analyzing efficiency of a fluid simulator which simulates a fluid flowing around an object by shortening the grid generating time of the simulator by improving the functions of the simulator for recognizing shape of object and for discriminating fluid and nonfluid area in a calculated area. SOLUTION: An analytical data generating section 3 is provided with a function which projects a hierarchical grid generated by adjusting roughness and fineness in a three-dimensional space upon a plane in the direction of each coordinate axis and defines the intersections of shape surface elements and a Descartes grid by sweeping grid points on the projected plane in the direction of a coordinate axis perpendicular to the projected plane, and based on the generated grid points, scans the intersection of the object surface most adjacent to the grid point in the directions of all coordinate axes and discriminates a fluid area when the inner product values of the normal vectors of the surface elements to which each intersection belongs and the distance vectors toward the grid points from the intersections are not negative and a nonfluid area in the other case. Thus, the grid forming time can be shortened and the fluid behavior analyzing efficiency of the simulator can be improved.
